Root: segments() splits on unquoted & so '2>&1' left rest[1]='2>', and any rest[1] not in the read-verb allowlist was treated as a mint key. Fix: a mint key must match /^[A-Za-z][\\w-]*/ (a real word like rent/commons), so redirects/operators/empty fall through to ALLOW (bare list). Real mints ('sidecar sign rent', 'sudo sidecar sign rent') still block; 'sidecar sign check rent 2>&1' still allows (rest[1]=check). Follow-up to #432."}
